Windows 7 Wired Network Configuration and Troubleshooting
Step 1: Checking the Cable
Your computer should be connected by a network interface card to the wall socket by a length of wire. This wire looks similar to a phone line, but the connections at each end are too wide to fit in a normal phone plug. Please ensure that this cable is present and secure on both ends. To do so, remove the cable and plug it back in. It should snap into place.
Note: If the cable is present and secure, try to access the internet. Your web browser should redirect you to the Hallnet login website. If it does not, continue these steps.
